Question: How Do You Present Epidemiological Data?

What is epidemiological data?

By definition, epidemiology is the study (scientific, systematic, and data-driven) of the distribution (frequency, pattern) and determinants (causes, risk factors) of health-related states and events (not just diseases) in specified populations (neighborhood, school, city, state, country, global)..

What are the 5 W’s of epidemiology?

The difference is that epidemiologists tend to use synonyms for the 5 W’s: diagnosis or health event (what), person (who), place (where), time (when), and causes, risk factors, and modes of transmission (why/how).

What are epidemiological features?

A key feature of epidemiology is the measurement of disease outcomes in relation to a population at risk. The population at risk is the group of people, healthy or sick, who would be counted as cases if they had the disease being studied.

Is an epidemiologist a doctor?

Are epidemiologists considered medical doctors? No. While epidemiologists study and investigate the causes and sources of diseases in much the same way as medical doctors, they’re not considered actual physicians. Perhaps the biggest reason why is treatment.

What are the two types of epidemiology?

Epidemiologic studies fall into two categories: experimental and observational.

What are the three components of the epidemiological triangle?

A number of models of disease causation have been proposed. Among the simplest of these is the epidemiologic triad or triangle, the traditional model for infectious disease. The triad consists of an external agent, a susceptible host, and an environment that brings the host and agent together.

How do you calculate epidemiological data?

Examples of sources of secondary data that are commonly used in epidemiological studies include birth and death certificates, population census records, patient medical records, disease registries, insurance claim forms and billing records, public health department case reports, and surveys of individuals and …

What is the purpose of epidemiological data?

Measures the progress of control and prevention programs. Enables generation of testable hypotheses regarding the etiology, exposure mode, control measure effectiveness, and other aspects of the health problem. Helps validate the eventual incrimination of causes or risk factors.

Who uses epidemiological data?

Who uses it? Researchers, health department officials, the government, and health or medical practitioners use epidemiology. This data is used to help identify priority health issues and possible causes of disease or illness.

What do epidemiologists do?

When disease outbreaks or other threats emerge, epidemiologists are on the scene to investigate. Often called “Disease Detectives”, epidemiologists search for the cause of disease, identify people who are at risk, determine how to control or stop the spread or prevent it from happening again.

What are the four methods of epidemiology?

Epidemiological studies generally fall into four broad categories:cross-sectional studies.cohort studies.intervention studies.

What is an example of epidemiology?

Epidemiological studies measure the risk of illness or death in an exposed population compared to that risk in an identical, unexposed population (for example, a population the same age, sex, race and social status as the exposed population).

What is risk in epidemiology?

In epidemiology, risk has been defined as “the probability of an event during a specified period of time” (2, p. 10). Below, we define risk as a function of time, allowing for competing risks (hereafter referred to as competing events) and more than 1 treatment (or exposure level) of interest.

What are the three types of epidemiological studies?

IntroductionObservational Studies. Case-Control Studies. … Cohort Studies. Cohort studies initially classify patients into two groups based on their exposure status. … Experimental Studies. Randomized Clinical Trials.

What are epidemiological measures?

Incidence, prevalence, and mortality rates are three frequency measures that are used to characterize the occurrence of health events in a population.

What are the 3 main elements of descriptive epidemiology?

In descriptive epidemiology, we organize and summarize data according to time, place, and person. These three characteristics are sometimes called the epidemiologic variables.

What are descriptive epidemiological methods?

Descriptive epidemiological methods characterize health events, health problems, and exposures in terms of person, place, time, and variability.

Where does epidemiological data come from?

Much of the data that epidemiologists collect comes from self-report—from answers provided by people participating in a study. For instance, an epidemiological study may collect data on the number of people who answer, “Yes” when asked if someone in their household has trouble hearing.
